Versatile Servo Drive VSD-E/XE (Evolution)

VSD-E & VSD-XE is a state of the art precision servo motor drive/controller for AC and DC servomotors and stepping motors. Possible control methods include position, velocity and torque modes. Built-in motion profiler enables simple point-to-point moves as well as continuous synchronous motion tracking.

VSD-E is perfectly matched to wide range of motors from 5 to 1500W, thanks to unique high dynamic range torque control (HDRT). Two independent current sensing ranges provide ultra low noise and high torque resolution, the most critical tool in position and velocity controls.

VSD-E features industry standard pulse/direction, quadrature, PWM and analog control inputs in addition to a device specific SPI (Serial Peripheral Interface) protocol. Drive supports encoder & hall sensors feedback. The VSD-E can be easily controlled from PC or LabVIEW with SimpleMotion library and also connection to fieldbuses like EtherCAT or CANopen (more info) is possible.

VSD-XE has the same technology equpped with machined high performance heatsink enabling higher continuous current ratings.

VSD-E & VSD-XE has been designed and manufactured in the northern Europe conforming the highest quality standards.
